Use of 4-hydroxydihydrochalcones and their salts for enhancing an impression of sweetness

摘要

The invention provides the use of
a 4-hydroxydihydrochalcone of the formula (I);
wherein
R1, R2, R3 and R4 each, independently, represent H, OH or O-alkyl, with the proviso that at least one of the groups R1, R2 or R3 represents OH,
a salt of such a 4-hydroxydihydrochalcone of the formula (I),a mixture containing or consisting of two or more different 4-hydroxydihydrochalcones of the formula (I), wherein R1, R2, R3 and R4 are each defined in the way given above,a mixture containing or consisting of salts of two or more different 4-hydroxydihydrochalcones of the formula (I), wherein R1, R2, R3 and R4 are each defined in the way given above

or
a mixture containing or consisting ofa 4-hydroxydihydrochalcone of the formula (I) or two or more different 4-hydroxydihydrochalcones of the formula (I), wherein R1, R2, R3 and R4 are each defined in the way given above, anda salt of a 4-hydroxydihydrochalcone of the formula (I) or two or more salts of different 4-hydroxydihydrochalcones of the formula (I), wherein R1, R2, R3 and R4 are each defined in the way given above,

to enhance the sweet taste of a sweet-tasting substance or the impression of a sweet smell of a flavoring that gives an impression of a sweet smell.

主权项

1. An oral hygiene or consumable preparation comprising:
(a) 0.1 to 150 ppm of phloretin (3-(4-hydroxyphenyl)-1-(2,4,6-trihydroxyphenyl)propan-1-one); and (b) one or more sweet-tasting substance selected from the group consisting of sucrose, glucose, fructose, maltitol, erythritol, sorbitol, mannitol, neohesperidin dihydrochalcone, thaumatin, stevioside, rebaudioside, and palatinose;
wherein the (a) phloretin, and the (b) one or more sweet-tasting substances in the preparation are in amounts such that the sweet taste of the sweet-tasting substance is synergistically enhanced by at least 1.2 times, in comparison to an otherwise identical preparation without the (a) phloretin;wherein the preparation is suitable for introduction into a person's mouth; andwherein the preparation:(a) contains no phloridzin, or(b) contains phloridzin, but the ratio of the amount of phloretin to the amount of phloridzin is greater than 1:1.
